You can create windows service, which will run on server once in 24 hours, which will send email depends on your business logic.

You can create it by using following link, which describes step by step guide,

i have to write code such that when user selects future date and button clicked mail should be received on that date just like e-cards.

Mukund Thakker 7-Jul-12 2:36am

If you needs to send future email, than store the information and date in database and check every day. if both date match than send email to recipient.

07405 7-Jul-12 2:42am

i am storing future date in database but how can i send on that particular date. i should not check daily it should sent automatically

Mukund Thakker 7-Jul-12 3:10am

If you are storing future date, than in windows service you can check like
select * from table where future_date=getdate
and send email to all the recipient.

If still you have confusion, share your code snippet.I will provide you full solution.

my query
Select * from Details where GETDATE()=DOB

protected void Button1_Click(object sender, EventArgs e)
{
cn.Open();
cm.Connection = cn;
cm.Parameters.Clear();

cm.CommandType = CommandType.StoredProcedure;
cm.CommandText = "getbirthdaydate";
SqlDataAdapter da = new SqlDataAdapter(cm);
da.Fill(ds);

foreach (System.Data.DataRow row in ds.Tables[0].Rows)
{

MailMessage msg = new MailMessage();
msg.From = new MailAddress("username");
msg.To.Add(ds.Tables[0].Rows[i]["Email"].ToString());
//msg.Bcc.Add(new MailAddress("bcc address"));
//msg.CC.Add(new MailAddress("cc address"));

msg.Subject = "subject of mail";
msg.Body = "message you want to send with email";
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
smtp.EnableSsl = true;

smtp.Credentials = new NetworkCredential("username", "password");

cn.Close();
smtp.Send(msg);
i++;
}
}

this is my code for normal mail sending.
but i have send that mail on tomorrow means how can i store this mail and send it on tomorrow. if i write services does it possible?

thank u for ur continuous reply..

Please add following code in service1.cs file
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;
using System.Timers;
using System.Net;
using System.IO;

namespace EmailSendingService
{
public partial class Service1 : ServiceBase
{

Timer objTimer = new Timer();
public Service1()
{
InitializeComponent();
//CHECK IF LOG FILE EXISTS ELSE CREATE NEW
if (!System.Diagnostics.EventLog.SourceExists("EmailSendingServiceLogSource"))
{
System.Diagnostics.EventLog.CreateEventSource("EmailSendingServiceLogSource", "EmailSendingServiceLog");
}

eventLog1.Source = "EmailSendingServiceLogSource";
eventLog1.Log = "EmailSendingServiceLog";
}

protected override void OnStart(string[] args)
{
try
{
int iHourIn24HourFormat = Convert.ToInt32(DateTime.Now.ToString("HH"));
int iCurrentMinutes = DateTime.Now.Minute;
int iCurrentSecond = DateTime.Now.Second;

int iFirstIntervalGapInHours = 24 - iHourIn24HourFormat;
eventLog1.WriteEntry("EmailSending Service Started ---->" + DateTime.Now.ToString());
objTimer.Interval = (1000 * 60 * 60 * iFirstIntervalGapInHours) + (1000 * 60 * 60 * 2) - (1000 * 60 * iCurrentMinutes) - (1000 * iCurrentSecond); // at 2:00 AM
eventLog1.WriteEntry("Interval -> " + objTimer.Interval.ToString());

objTimer.Enabled = true;
objTimer.Elapsed += new ElapsedEventHandler(objTimer_Elapsed);
objTimer.Start();
}
catch (Exception ex)
{

eventLog1.WriteEntry("Error: " + ex.Message);
}
}

protected override void OnStop()
{
}
void objTimer_Elapsed(object sender, ElapsedEventArgs e)
{
try
{
eventLog1.WriteEntry("Timer Elapsed ---->" + DateTime.Now.ToString());

objTimer.Interval = 1000 * 60 * 60 * 24; //set interval for every 1 day

ContinueProcess();
}
catch (Exception ex)
{
eventLog1.WriteEntry("Error: " + ex.Message);
}
}

private void ContinueProcess()
{
try
{
HttpWebRequest objHttpWebRequest = (HttpWebRequest)WebRequest.Create("http://www.website.com/send-future-email.aspx");
objHttpWebRequest.Method = "Get";
objHttpWebRequest.ContentLength = 0;
HttpWebResponse objHttpWebResponse = (HttpWebResponse)objHttpWebRequest.GetResponse();
Stream objResponseStream = objHttpWebResponse.GetResponseStream();
}
catch (Exception ex)
{
eventLog1.WriteEntry("Error: " + ex.Message);
}
}
}
}

Please add code inside Button1_Click event in send-future-email.aspx in page_load.

When you setup the service, it will call the page every day and it will send email to all user who is having birth day today.

Do not forgot to mark as answer if it helps you.

Mukund Thakker 7-Jul-12 5:16am

Yes, add service in same project.
http://msdn.microsoft.com/en-us/library/zt39148a.aspx
Check above url for step by step guide in creating windows service.
And add send-future-email.aspx page in your website.

Mukund Thakker 7-Jul-12 5:14am

Do not add any button in the page. Just create send-future-email.aspx and in page_load add following code,

cn.Open();
cm.Connection = cn;
cm.Parameters.Clear();
cm.CommandType = CommandType.StoredProcedure; cm.CommandText = "getbirthdaydate"; SqlDataAdapter da = new SqlDataAdapter(cm); da.Fill(ds); foreach (System.Data.DataRow row in ds.Tables[0].Rows) { MailMessage msg = new MailMessage(); msg.From = new MailAddress("username"); msg.To.Add(ds.Tables[0].Rows[i]["Email"].ToString()); //msg.Bcc.Add(new MailAddress("bcc address")); //msg.CC.Add(new MailAddress("cc address")); msg.Subject = "subject of mail"; msg.Body = "message you want to send with email"; SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587); smtp.EnableSsl = true; smtp.Credentials = new NetworkCredential("username", "password"); cn.Close(); smtp.Send(msg); i++; }

Which you have added in button1_click event.

Mukund Thakker 7-Jul-12 6:54am

You can install windows service on hosting server.

how to install windows service on hosting server.can u tell me clearly

Mukund Thakker 7-Jul-12 8:21am

Which hosting server do u have?
Shared or dedicated?

Mukund Thakker 7-Jul-12 8:25am

If you have dedicated server, you can directly install the setup file, similar to other setup program you install.

you can call this function as per your requirement

function:-

C#

public bool sandMail(string strTo, string strfrom,string password,string strSubject, string strBody)

{ MailMessage mailObj=new MailMessage();
SmtpClient clientObj = new SmtpClient();
clientObj.Credentials = new System.Net.NetworkCredential(strfrom, password);
clientObj.Host = "smtp.gmail.com";
clientObj.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
clientObj.EnableSsl = false;
clientObj.Port = 587;
MailAddress mailadTo = new MailAddress(strTo);
MailAddress mailfrom = new MailAddress(strfrom, "rizwan");
mailObj.To.Add(mailadTo);
mailObj.From = mailfrom;
mailObj.Subject = "hi";
mailObj.IsBodyHtml = true;
clientObj.Send(mailObj);
return true;
}
